La Barra Brava: Why US football fans chant in Spanish
4 June 2014 Last updated at 00:58 BST
Every time DC United plays in Major League Soccer, a group of fans get their drums and their flags and support their team in Spanish - even though many of them don't even speak the language.
Inspired by the passion of supporters across Latin America, the Barra Brava has become one of DC United's loudest fan groups, as well as a melting pot of nationalities and cultures.
The BBC met Barra Brava founder Oscar Zambrana and Jay Igiel, one of the group's leaders, at a recent match.
